HID D1S Ballast for Mercedes GLK300 GLK350 BMW 3 Series 4 Series X3 F25
Restore full nighttime visibility while keeping your vehicle’s original headlight wiring intact with this D1S Xenon HID ballast control unit. Designed to OE specifications, this replacement component directly addresses flickering low beams, delayed warm-up periods, or complete signal loss in modern xenon lighting systems.
Engineered as a precise substitute for Bosch Gen6 technology, the unit plugs directly into your existing harness without cutting wires or requiring software coding. Internal circuitry is rigorously run-tested to deliver consistent voltage output, reducing premature bulb failure and maintaining accurate beam alignment. Whether you operate a 2012–2014 Mercedes GLK class, a BMW F-series sedan, a Cadillac CTS, or a Kia Optima, this ballast restores crisp, steady illumination exactly as the factory designed.
Benefits & Practical Advice
- Direct Plug-and-Play Swap: Match the original connector pinout and mounting bracket geometry to replace faulty units in under fifteen minutes using basic hand tools.
- Moisture Management: Seat the new ballast securely within its housing or undertray after replacing the lens gasket to prevent condensation from triggering error codes.
- Synchronized Replacement: When installing a unit approaching the four-to-five-year service window, pair it with a fresh D1S xenon lamp to avoid mismatched color temperature and brightness decay.
